what is the substrate for a antigen and b antigen synthesis?
Answer:
The blood group A antigen is synthesized by an N-acetylgalactosaminyltransferase that uses a UDP-α-N-acetylgalactosamine (UDP-GalNAc) as sugar donor substrate, while the B antigen is synthesized by a galactosyltransferase that uses a UDP-α-galactose (UDP-Gal) as a sugar donor substrate.
The substrate for A antigen is N-acetylgalactosaminyltransferase which uses a UDP-α-N-acetylgalactosamine (UDP-GalNAc) as sugar donor substrate and the substrate for B Antigen is galactosyltransferase which uses a UDP-α-galactose (UDP-Gal) as a sugar donor substrate.

PLS FAST!! WILL GIVE BRAINLIEST!! 30 POINTS!! About one-third of Americans will suffer from an anxiety disorder at some point in their lives. About one-quarter will experience a serious depressive episode. Although therapy can reduce symptoms of depression and anxiety, many people do not seek professional help.
What internal factors might make people more or less likely to seek help? Internal factors might include the person’s mood, thought patterns, energy levels, feelings of hopelessness, attitudes toward mental health providers, and so on.
What external factors might make people more or less likely to seek help? External factors might include time, cost, the attitudes and expectations of friends and family, and so on.
Given these factors, what changes in our society might lead more people to seek help?
Answer:
Changes in our society that might lead to more people seeking help for anxiety disorders are if people were more open to talking about it. Also if people knew more about how the treatment actually works. If they know more about the process or if they knew they could get treated for their anxiety there is a higher chance that they might go get treated.
Explanation:
While prior research suggests that the most common reported reason people with SAD or GAD haven't gotten care is out of fear of what others will say or think, showing how powerful stigma really is, other common reasons include lack of financial resources and not knowing where to go for care.
Anxiety, like many other mental health conditions, can be harder to treat if you wait. Keep a journal. Keeping track of your personal life can help you and your mental health professional identify what's causing you stress and what seems to help you feel better.
